Loki looked half-dead before, it's cool he mustered up that great attack but it's best Luffy could handle him easily after that. He'll heal up and we'll see where things go from there. It's fine for him to explain himself to his brother, but I hope all that talk of destruction and killing doesn't completely vanish. I don't know, I also kinda just want to see Luffy vs Loki.
I'm glad we're seeing more of the Holy Knights. Killingham's fruit is pretty great, and Sommers isn't bad either. I look forward to seeing them in full on fights and seeing how they're countered or overcome. Hope Gunko gets something to do as well, I want to see more of her fruit.
